V Referringtotheldrawing the numeral 10 indicatesthe main frame of the ensilage and silo ,cutter which is provided with the usual revoluble cutter 11 mounted on. the drive shaft; .12 and inolosed in the casing 13andpo= sitioned to engagethe stationary cutter. 1 s rigidly connected to the frame. Two feed and compression rollers15 and 16 respectively are, positioned immediately in front of the cutters andserve tolcompress, and feed the material to thecutters. I The lower feed roller 15 is carried by a shaft 17 journaled ina fixed: portion] of the frame andthe-.upper roller 16'is carried by. a shaft 18- journaled in links 19Fwhioh are 1 pivotally connected toan apron shaft 20. The upper feed roller is longitudinally ribbed and .is yieldinglyand adjustably held inengagement with. the lower roller by means of spring lever bars 21 which are. connectedto the links-19 hy;rods 22 .andat. points near their opposite, ends are fulcrumed against. a transverse portion of; the main frame and their ends are connectedto the mainframe by bolts 23. The-bolts 23.21 1161 the rods 22 are provided with nuts 24:; threaded thereto to adjust-the tension of said spring bars;

Theendless conveyer-ZS which is formed of. side. chains 29 jjQln eCl together by transverse slats 3.01 163 carried on sprocket wheels 31 mountedmn theouter end ofthe frame and 1 a-drnmi32z ii i ly m t on a a t which is journaledz-within thecasing of the ramell e r=l 1 e e$-. to P n h i e-i eriah rom; fal ing t ough. e. paces ber rolls and 16. Theendless conveyer-34 is tween the transverse slats and is recessed longitudinally to accommodate the slats and to form ribs 33 which assist in feeding the material into the machine.

A floating endless feed apron 34 positioned at an angle above the inner end of the endless conveyer 28 isadapted to assist in.

drawing the material into the machine and at the same time compress or flatten 1t so 1t will easlly pass between the compression also formed of side sprocket chains 35 joined together by transverse slats 36 and is carried on drums 37 and 38. These drums also form a solid backing forthe conveyer slats and are provided with longitudinal recesses toaccommodate the said slats and also form ribs 39 to engage and move the material.

- pending from the main frame.

38. is rigidly connected to and turns with the I A. swinging frame 410 having mounted thereinthe apron shaft 20 and another shaft 4cl-is pivotally suspended from links 42 de- The drum shaft 20 while the drum 37 is loosely mounted on the shaft 41 and acts as an idler drum. Transverse boards 61:3 connect the two sides I of thefswinging frame together and serve as 'a backing for the endless apron. The pivotal'connection of the swinging apron frame 10 to the casing of the machine and the linked connection-with the compression shaft 18' permits the apron to yieldingly bear on the material passing between the I conveyer and the said apron.

" The'maindrive shaft 12 is provided with a flywheel 4:3. and a belt drive wheel 44 on V onesideof the'main'frame and with a pinion 15' on the shaft extending through the easing onthe'other side of the casing. A swinging gear frame 46 having pinions A7 and A8 and gear 49 mounted thereon is pivl otally supported on the main drive shaft 12. The gear l9 is in constant mesh with the main drive shaft pinion 15 and the pinion 4:8 which is rigidly mounted on the same shaft which carries the gear49 is in constant mesh with the pinion 47. The pinions l7 and 4:8

to be swung into mesh with the internal gear depending upon the direction of movement of the feed desired. The gear frame is swung to move either pinion into mesh with the internal gear tochange the direction of rotation of the internal gear by means of a reversing lever 51 which has a linked connection52 with the'gear frame 16. When the reversing lever is swung to theright, as shown in the drawings, the parts will rotate in a direction to feed material to the cutter,

and when swung in the opposite direction the direction of feed will be away from the cutter; and when the handle is positioned in .a medial position the reversing pinions will both be out of mesh with the internal gear and the feeding mechanism will be inoperative. The lever is provided with a spring 53 which holds said lever in the notched portions of the sector 54 fastened to the frame to hold said lever in adjusted position.

The compression roller shaft 17 and the conveyer shaft 32 are provided with gears I gear 64 rigidly connected thereto and which meshes with the gear wheel 60. A sprocket wheel 65 mounted on the shaft 18 and turning therewith derives its motion from a sprocket chain connection 66 with the sprocket wheel 61 and the adjustable arm 58 provides the means for taking up the stretch in said chain to compensate for the wear thereof. The opposite end of the shaft 18 and the shaft 19 are provided with sprocket wheels 67 and 68 respectively which are connected together by a sprocket chain 69, thus providing means for transmitting motion to the endless apron and permit it to freely swing up and down with. the feed of the material. I

The shaft 20 extends through openings 70 provided in the casing which are shaped to permit said shaft to swing in different arcs of movements without striking said casing. The casing is also provided with curved guide slots 71 through which the shaft 18 extends and is guided. These slots 71 are curved concentrically with relation to the shaft 20 when in its owermost position so that the shaft 18 may swing upwardly when said shaft 20 is in its said lower or other positions.

The swinging apron frame is rovided with a screw adjustment means 7 2 or tightening the apron 34:.

In the operation of the machine material dropped upon the endless conveyer will be carried thereby beneath the yielding or floating apron which will tend to draw the material into the casing of the machine and at the same time compress it so it will easily pass into engagement with the compression and feed rolls and be further compressed thereby into a compact mass and then fed to the cutter which will cut it into small pieces. The floating apron and the yielding compression rolls will feed the varying quantities of material dropped on the conveyer and if the machine should become clogged the operator can momentarily reverse the direction of feed by swinging the reversing lever without stopping the operation of the cutter and thus clear the machine tive without interfering with the operation of the cutter.

As the conveyer extends out of the casing beyond the path of movement of the feed rolls and the cutter there is no danger of the operator becomingaccidentally injured by copliing in contact with the cutter or feed re s.

From the foregoing description it will be seen that the feeder is simple in construction and operation and is inexpensive to manufacture and maintain.

What I claim as my invention is:

1. A self feeder comprising a frame, an endless conveyer mounted upon the frame, a rotatable apron positioned above the conveyer and swingingly mounted on the frame to move vertically and longitudinally thereof, feed rolls mounted on the frame, and means connecting one of said rolls and the lower end of the apron to permit said roll and apron to'be moved on the frame and relative to each other.

2. A self feeder comprising a frame, an

endless conveyer mounted upon the frame,- a rotatable apron positioned above the conveyer and swingingly mounted on the frame to move vertically and longitudinally there of, feed rolls mounted on the frame, and a link connection between one of said rolls and the lower end of the rotatable apron to permit said roll and apron to be moved on the frame and relative to each other.

8. A self feeder comprising a frame, an endless conveyer mounted upon the frame, a .rotatable apron positioned above the conveyer, said apron being mounted on upper and lower drums, means for pivotally and swingingly mounting the lower drum and one of said feed rolls, said roll and apron being free to move with respect to the frame and to each other.

4. A self feeder comprising a frame, an endless conveyer mounted upon the frame,

an apron-frame swingingly mounted on said frame, a rotatable apron mounted on the apron-frame to move vertically thereof, feed rolls mounted on the frame, and means connecting one of said rolls and lower end of r the apron to permit said rolls and apron to be moved with respect to the frame and relative to each other. 5. A self feeder comprising a frame, a

endless conveyer mounted upon the frame,

an apron-frame swingingly mounted on said frame, a rotatable apron mounted on the apron-frame and movable with respect thereto, feed rolls mounted on the frame, a link connecting one of said feed rolls and the lower end of the apron to permit said roll and apron to be moved with respect to the frame and to each other, and yielding means connected to said roll whereby said roll and apron will be yieldingly supported.

In testimony whereof, I affix my signature, in presence of twowitnesses.
